Any set of party ideas that uses the phrase “_____ is forbidden” loses my vote.
There are too many rulebooks for etiquette, these days. The problem is, they have a hard time distinguishing themselves if they all say the same thing, but if they don’t, the unified framework for politeness falls apart.
More importantly, who cares? Would you remember a party with flawless etiquette better than one that was well and truly fun? (Granted, it depends on the kind of fun we’re talking about..)
I didn’t think so.
